That’s what a new book from Harvard says
The overview of a new book edited by Richard Rosecrance and Arthur Stein is interesting enough to be quoted almost in extenso:
The twentieth century witnessed an explosion of new nations carved out of existing ramshackle empires and multiethnic states. Many observers contend that the creation of new states will continue indefinitely, with the two hundred of today becoming the four hundred of tomorrow as more groups seek independence. This provocative and compelling book explores the impact of globalization and terrorism on this trend, arguing convincingly that the era of national self-determination has finally come to an end.
Examining the forces that determine the emergence of new nation-states, the distinguished contributors consider a rich array of specific cases from the Middle East, Asia, North America, Europe, and Russia where new states could be created.
They contend that globalization, rather than expanding such opportunities, is not as friendly to new weak states with limited resources as it is to established rich nations. Given the vast sums circulating in the world market, few fledgling nations can be financially independent. They find it more prudent to shelter within the protective embrace of existing federations. Equally, governments of federal states can induce restive petitionersâ€”such as Quebec, Scotland, and the Basquesâ€”to remain inside the metropolitan boundary through a system of tangible restraints and rewards. Those who reject the benefits, such as rebels in Chechnya and Aceh, will fail in their bids for independence. Taiwanâ€”poised on a knife-edge between integration with China and independenceâ€”faces a series of costs and diminished returns if it seeks full statehood. Finally, terrorism has lost its legitimacy as a technique for gaining independence in the eyes of the international community.
On balance, the book concludes, discontented national movements will have to find ways to exist within current geopolitical boundaries. [Belfer/KSG/Harvard]
Indeed, national self-determination has been given an indiscriminate halo over the last century, allowing anything ranging from religious partisanship to undisguised xenophobia to pass off under that exalted label. What is more important in the contemporary age is improving institutions to make them democratic, tolerant and protective of individual, economic, social and political freedoms. In the 21st century morality is more correctly invested in countries that uphold these values.
